ABSTRACT:
A heat-generating member (4) is arranged in a water-filled pressure vessel (1) which is provided with a pressure relief valve or the like. The water of the pressure vessel can be partly evaporated, thereby acting as a heat sink for the generated heat. The walls of an outer vessel (6) surround at least a lower part of the pressure vessel (1) in such a way that a closed, relatively small auxiliary space (7) is formed between the two vessels. The auxiliary space (7) communicates via at least one tube (8) with an open evaporation pool (9), which is arranged above the cover (2) of the pressure vessel (1). A tube coil (10), disposed in an upper part of the pressure vessel, is connected by both ends to the evaporation pool (9). If a leak (13) should occur in the lower part of the pressure vessel, water from the auxiliary space flows to the evaporation pool via the tube 8 and from the evaporation pool into the tube coil (10), whereby boiling takes place in the evaporation pool (9) due to high-temperature steam condensing on the tube coil. The leakage (13), thus, does not result in a loss of the heat sink.
